Re: What's the best way to clean up valve seats & a couple other questions
I agree with #3 and #4 being a bit oily, especially #4. Clean up the bores in those holes with a rag and some gas and see what they look like then. I don't see any real issues with the valves,but... What was the compression ? Was a valve or two leaking ? Why do you want to do the valves, because of the excessive valve lash ? Anyway, a wire brush will clean up the valves and seats. Did you find a valve grinding machine ?
